Until the 1980s, the United Kingdom enforced no statutory separation of
banking and securities industries, but distinguished between them as a
matter of custom. The Bank of England supervised banks.
Securities firms—firms that broker or
deal in securities—were traditionally self-regulating. The 1986 Financial Services Act
changed this, establishing separate regularity functions for banks and
securities firms.
Germany had a tradition of universal banking, which made no distinction
between banks and securities firms. Under German law, securities firms
were banks, and a single regulatory authority oversaw banks. France and
the Scandinavian countries had similar regimes. Accordingly, Europe
supported two alternative models for financial regulation:
the Continental, or German model of universal banking,
and
the Anglo-Saxon or British model of
separate banking and securities activities.
The European Union (EU) had a goal of implementing a common market by
1993. As the nations of Europe moved towards integrating their economies,
the two models of financial regulation came into conflict. New EU laws
needed either to choose between or somehow blend the two approaches.
The issue was settled by the 1989
Second Banking Coordination Directive
and the 1993 Investment Services Directive. These granted European nations
broad latitude in establishing their own legal and regulatory framework
for financial services. Financial firms were granted a “single passport”
to operate throughout the EU subject to the regulations of their home
country. A bank domiciled in an EU country that permitted universal
banking could conduct universal banking in another EU country that
prohibited it. With France and Germany committed to universal banking, the
single passport model effectively opened all of Europe to universal
banking. It also permitted Britain to maintain a separate regulatory
framework for its non-bank securities firms.
Since the securities operations of Germany’s universal banks would be
competing with Britain’s non-bank securities firms, there was a desire to
harmonize
capital requirements for the two. The solution implemented with
the 1993 Capital Adequacy Directive (CAD) was to regulate functions
instead of institutions.
The CAD established uniform capital
requirements applicable to both
universal banks’ securities operations and non-bank securities firms. A
universal bank would identify a portion of its balance sheet as comprising
a “trading book.” Capital for the trading book would be held in accordance
with the CAD while capital for the remainder of the bank’s balance sheet
would be held in accordance with the 1988 Basel Accord, as implemented by
Europe’s 1989 Solvency Ratio Directive. Bank capital was conservatively
defined according to the 1989 Own Funds Directive, but local regulators
had discretion to apply more liberal rules for capital supporting the
trading book.
A bank’s trading book would include equities and fixed income
securities held for dealing or proprietary trading. It would also include
equity and fixed income
OTC
derivatives,
repos, certain forms of
securities lending and exposures due to
unsettled transactions. Foreign
exchange exposures were not included in the trading book but were
addressed organization-wide under a separate provision of the CAD.
A minimum capital requirement for the
market risk of a trading book was
based upon a crude value-at-risk (VaR) measure intended to loosely reflect a 10-day 95%
VaR metric. This entailed separate “general risk” and “specific risk”
computations, with the results summed. The measure has come to be known as
the “building-block” approach.
Europe developed the CAD at the same time that the
Basel Committee was
developing an amendment covering market risk for its 1988 capital accord.
The two initiatives influenced each other. Essentially, Europe was
pursuing locally what Basel was pursuing globally. European regulators had
hoped that both initiatives could be completed simultaneously, but this
was not to be. The EU had set a deadline of 1992 for reaching agreement on
all significant single-market legislation. The Basel Committee's work
continued until 1996. Accordingly, the CAD was passed three years before
the 1996 amendment to the Basel Accord was complete.
In 1993, the CAD and proposals for the Basel amendment were very
similar. Both calculated capital requirements for a trading book based
upon a building-block VaR measure. By 1996, the Basel amendment had
evolved. It retained a building-block VaR measure as one option for
calculating market risk capital, but it also allowed banks, under certain
circumstances, to use their own internal (and presumably more
sophisticated) VaR measures. Because CAD did not provide for the use of
internal VaR measures, European banks were potentially at a competitive
disadvantage compared to banks outside of Europe. To address this issue,
Europe rushed passage of an update to CAD, called CAD II. This was
somewhat of a stopgap measure. It allows European banks to base capital
requirements on internal VaR measures, but it remains inconsistent with
the 1996 Basel amendment in other respects. A new CAD III
will implement the Basel II Accord.
